+## Smart Device Control
+
+Motion Recorder can automatically control lights and switches based on its current state.
+
+### How It Works
+
+1. Select one or more `light` or `switch` entities in settings
+2. Choose which states should trigger the devices (e.g., `recording`, `delaying`)
+3. When the integration enters a selected state → devices turn ON
+4. When it leaves that state → devices turn OFF (only if integration turned them on)
+
+### Safety Features
+
+- **Non-intrusive**: If you manually turn on a light, the integration won't turn it off
+- **Manual override respected**: If you turn off a controlled light during recording, it stays off
+- **Shutdown cleanup**: All integration-controlled devices are turned off when HA restarts or integration reloads
+
+### Example Use Cases
+
+- Turn on porch light only while recording is active
+- Activate alarm indicator LED during motion detection
+- Turn on indoor lighting when camera detects movement at night
+
 ## Advanced Features
 
 ### Multiple Motion Sensors
